A few weeks ago we got stuck in a field and after spinning tires after a few attempts, I had to have a tractor pull us out.

I have TPMS sensors on each valve stem but once in a while they act screwy and I shut the receiver off before we left TN.

Last week I was under the RV trying to fix the air suspension and I noticed the right inner tire looked low. I put a gauge on it and it didn't register.

I used the air suspension to raise the DX3 and pump air into the tire. It never popped but had 102 lbs in it when I was finished. I drove it around the shop to make sure it seated and while I didn't hear it pop, it looked like it was now sealed around the rim.

I'll check it Monday but was wondering, has this ever happened to anyone? IF it came off the rim a few weeks ago while spinning the tire, that means I drove all the way back from TN to NC with one tire on the right rear.

Like I said, I'll check on it again Monday and if it measures low, I'll take the tire to a truck shop and get it looked at.

I doubt if the tire would have survived a trip that long without any air pressure. The air lose may have resulted from spinning spinning it by getting crud between the rim and tire. I personally would have the tire removed, checked for damage, and remounted. My piece of mind is worth more that the money spent to get it checked.

The only times I have heard the tire coming off the rim is when they are the wrong size for the rim or through a traumatic incident. But the tire should not have survived a long drive without air. Do have it checked or replaced as it is probably damaged.

I would suspect a slow leak, possibly the valve stem, TPMS leak or something in the tire. I agree with Bob that it wouldn't have made it home with little or no air pressure. I have experienced several "flats" on the inside rear and it feels like the wheel is coming off, just before it tears the heck out of the wheel shroud.

apples to oranges but here's my tale.... a long time ago when I was a young man I may have driven a little faster and more wreckless...
I spun out on a gravel road and hit the ditch pretty hard. The car stayed on all 4 but just barely. When the dust settled I backed out of the ditch and drove home.
Later I noticed one tire flat on the car. I took it off and to a tire shop.
He dis-mounted the tire and proceeded to get nearly a cup of gravel and dirt out of the tire.
I am absolutely sure the tire wasn't flat when I got home. It had pushed off the rim far enough to scoop up all the gravel and then half way re-seated. At least enough for the 5 minute drive home.

If the motorhome has commercial half size diameter rims, like in 17.5, 19.5, 22.5...they are not made like whole travel trailer/5th wheel diameter sizes and have a different bead to rim mounting surface. If these type tires get low, it's very easy for their bead to come away from the rim.

These commercial tires also do not "pop" out on the rims which I think the OP was stating he did not hear.

I agree with all above. If the tire was really low or flat on your trip the outer tire would have been overloaded and could possibly blown out. That would leave you with 2 flat tires and damage to the coach....just dont ask how I know this...

I would find a truck shop that has a tire man who has been TRAINED in tire inspection. Tell him exactly what happened. At the very least, I believe the "suspect" tire needs to be removed and CAREFULLY inspected. I would not be surprised if the tire inspection specialist recommends that ALL tires on that axle be properly inspected. Tires/wheels/bearings/axles etc all work together as a system. When one component of a system fails, it DOES affect other parts of that system. If a tire needs to be replaced, don't be surprised if you're told that the other tire needs to be replace as well because, dually tires have to be very close in size (actual diameter). If the otherwise "good" dually has significant wear due to normal use, that may well need replacing just so both duallies match.
